.This invention relates to windowscree'ns and more particularly to thetype adapted to-lfbe Wound. on a spring-roller.

The principal object of the present invention is to provide a rollingwindow screen which is adaptable to any type window, such as sash,

provide a rolling window screen which when unrolled is completely sealedand affords the utmost in protection against insects and similar pests,regardless of size.

Another object of the present invention is to provide a dust-proofcompartment for receiving a rolling window screen and having meansinternal thereof for rendering a spring-roller operable.

Another object of the present invention is t provide a rolling windowscreen adapted to be unrolled upon the raising of a lower sash totherebyscreen the opening thus afforded, and .to be rolled when saidsash is lowered; or to be unrolled upon the lowering of an upper sash tothereby screen the opening thus afforded, and to be rolled when saidsash is raised.

Another object of the present invention is to provide means by which arolling window screen maybe locked to and easily detached from a windowsash or sill when so desired.

Another object of the present invention is to provide means for theuniform lifting and lowering of a rolling window screen to therebyassure an ease of operation and the proper rolling there- Another objectof the present invention is-to provide bracketing means whereby thescreen enclosing compartment may be easily affixed to a window frame.

-- For further comprehension of the invention,

and of the objects and advantages thereof, reference will be had to thefollowing description and accompanying drawings, and to the appendedclaim in which the various novel features of the invention are moreparticularly set forth.

In the accompanying drawings forming a ma- Fig. 1 is a front elevationalview illustrating the present device screening the entire opening of awindow.

1 Claim. I (01. 160-23) screen enclosing compartment and the bracketsfor the mounting thereof.

Fig. 3 is a fragmentary isometricview of-one end of the compartment andthe screen roller.

Fig. 4 is afragmentary isometric view of the other end of thecompartment and screenroller.

Fig. 5 is a fragmentary view illustrating the screen locking and screensealing means.

Fig. 6 is an isometric view illustrating the present device as adaptedto screen the opening effected by the raising of a lower window sash.

Fig. 7 is an isometric view showing the present device adapted to screenthe opening effected by the lowering of an upper window sash.

In Fig. 1 the frame l0, comprising a roof ll, left and right sideupright members l2 and I3, respectively, and a sill l4, represents anywindow frame, be it that of a sash, casement, or any other type. Thecompartment l5 fits between the side members l2 and i3 and is bracketedthereto by left and right-hand brackets l6 and [1, respectively, whichare seen better in Fig. 2. Said brackets l6 and H are provided withbent-over rear and bottom portions l8 and I9, respectively, and whenproperly mounted to their respective side members l2 and I3 are adaptedto receive therebetween the compartment I5, the rear bent-over portionsl8 limiting the rearward extent of movement of the compartment l5 andthe said bottom bent-over portions l9 providing support to saidcompartment. As also seen in both Figs. 1 and 2, an

angle strip 20 is centrally disposed on and fixedly secured, as by spotwelding or similar means, to the front of the compartment I 5, and isprovided with a hole 2! for receiving a screw or nailin order that saidcompartment may be secured in a proper operating position between thesaid brackets l6 and I1.

Fig. 1 also illustrates the manner in which the rolled screen 25, whichwill be described in detail hereinaftenis completely hidden in the saidcompartmentsflli'i. band the sealing channels 26 and the lockingmeansZI, both of which will also be described hereinafter.

The roller 24 having the screening material 25 rolled thereon and seenin Figs. 3 and 4 is similar to the well-known spring-rollers used inwindow shades, and it will be suflicient'herein merely to indicate thatone end is provided with a stationary pivot pin 2t while the springmechanism end is provided-with a revolvable fiat pin 29.

Fig. 2 is an isometric view illustrating the 58 welding or similarmeans, is a pivot bracket 30 removed from the slots 32 and 33 and thepivot pin 28 is first positioned in the bracket. 30,.then the flat pin28 is inserted in its related bracket 36.

Subsequently, the bracket slide 35 is inserted.

in the slots 32 and 33, and therestraining action 2, 3 and 4,.a.cut-outslot 31' in the underside of the compartment l5 permits. thepassage therethrough of the screening material 25.

Now, in' order; that the screening might be sealed to prevent thepassageof 'insects'orbther like pests between the sides thereof and theupright side members !2 and E3 of the window frame 59, and in order thatsaid screen may be raised and'lowered easily and guided to rollproperly, sealing channels 26 are provided and are screwed or nailed tosaid frame side members ['2 and i3. Said sealing channels 26 may be ofany required length and of any suitable'material; and as best seen inFig. 5 are preferably formed of flat sheet metal strips foldedlengthwise upon themselves and each having its sides 38'and139 bent overin the same direction to thus form a channel 40. The screening 25'hasattached at the freeend thereofa rigid cross member 2!; the ends ofwhich and the sides of thescreening being adapted to fit slidably in theaforementioned channels 43 of' the left and right-hand sealing channels26.

As also well seen in Figs; 1 and 5 each of the hereinab'ovementioned'locking means 2 7 comprises an angle member 43-;the'uprig-htleg thereof being secured as at 44 to thesaid screen crossmember 4'! and" having provided in'its horizontal leg a rectangularaperture 45; and a turn bolt 4'6 adapted to 'pass'through the'saidaperture-45 when aligned therewith and not to be passable therethroughwhen turned'through an angle or: Slide.- grees. In both. Figs; l and-'5the turn" bolts. 45 are'mount'ed on thawin'dow sill l4 and' the screen25 is'lockablethereto. when rolled downand the said turn? bolts arepassed through. theis'a'id aper tures45 and turned QOdegrees. Whemitiis'desired that: the screens-be opened the turn. bolts 43' are aligned withthe apertures. 4'5 and with the assistance of the spring-roller 24 thescreen is rolled up;

The just described arrangement providesxfor the: screening of' an entirewindow. However, as shown: in Fig; 6', the present invention is. also applicable. to: the-screening: only ot the opening effected by theraising. of alower Sasha-41w and may be-arranged to cooperate with saidlower sash and be unrolled by the. same action with which the sash israised. This modification provides-for the compartment IE-being mountedbetweenthe lower ends of the side members I2- and I3 of the frame. Ininthe brackets 16- and H and held in position. by the. angle strip. 20secured to the. sill |4.- A150, the sealir'i'ezv channels 25 areofi'on'ly half-lengths and the above described turn bolts 46 are mountedon the upper side of the lower cross member 48 of the said sash 41. Withthis arrangement it will be seen that, when the screen is locked to thesash 4! by means of the turn bolts 46 and the angles 43 and the windowis closed the screen is completely rolled and hidden in the compartmentl5, and when the sash is raised the screen is automatically unrolledaccordingly. Thus, protection is provided at all times during theopening of the window.

. A similar arrangement is shown in Fig. 7 whereby the opening affordedby the lowering of the uppersash 50 is screened and the screen isautomatically unrolled through the sash lowering operation. Here, as inFig. 1, the compartment 15 mounted between the upright members I! andI3. of the frame In in brackets l6 and I1 and held in position bytheangle strip 20 secured to the frame roofv ll- But, as in the lastdescribed modification, the sealing channels; 26. herein employed arehalf-lengths. Now, differing frornsaijd last described modification; thesaid turn bolts 46 are herein mounted on the underside of the uppercross member 5| of the said upper'sash 50. Therefore, when thelockingmeans 21 are effective, it will be seen that the lowering'ot the uppersash 50 effects the .unrolling of the screen 25' and affords the utmostprotection against the entrance of insects, and that the raising of saidupper sash 59 effects the rolling'of said screen 25.

It will be noted that in all of the above described arrangements, thecompartment l5 when in its operativ position has its open side coveredby either the frame roof H or window sill HI, thus having its innerelements protected at all times I from dust or other foreign damagingmatter.

While I have illustrated and described the preferred embodiments of myinvention, it is to be understood that I do not limit myself totheprecise constructions herein disclosed and the right is reservedto allchangesjand modifications'coming within the scope of the'invention asdefined in the appendedfclaim.

Having thus described my" invention, what I claim as new, and desiretosecure'by United States Letters'Patent is Y 4 I In a rolling screenhaving a spring-roller with screening material rolled thereon and" apivot pin at one end of the roller and -a;fla't pi'n at the spring endof the roller, a compartmenthaving one side open, a pivot bracketsecured at'one end of said compartment for-receiving the pivot pin,apair. of slide. receivingslotsat'the other end of said compartment, abracket slidably fitted -in said slots, and a restraining" bracketsecuredv to said bracket and the: fiat pin' being insertable into saidrestraining bracket when said first bracketis removed from-said slots.
